Happy Valley is so effective at what it sets out to do, and so neat in fitting all its pieces together (up to the way the story's climax evokes a much milder incident from early in the series), that I'm a bit ambivalent about the fact that a second season has already been ordered. Lancashire is so good that I won't necessarily mind getting to watch more of her in this role, but this particular story is so unique to her in a way that no sequel season can be.

It’s hard to do the show justice, honestly, based strictly on a description. But the characters are so sharply drawn and the situation so suspenseful that Netflix’s famous binge function will likely be put to good use here.
